Eczema (a.k.a. Atopic Dermatitis)
Mayo Clinic (.com) describes Eczema (Atopic Dermatitis) as a condition that makes your skin red and itchy. It’s common in children but can occur at any age. Atopic dermatitis is long lasting (chronic) and tends to flare periodically and then subside. It may be accompanied by asthma or hay fever.
Eczema is based upon complex interactions of genetic predispositions, environmental triggers, and immune dysregulation.

Irritated and swollen airways which have difficulty properly carrying air to and from the lungs is known as Asthma. Common symptoms include: wheezing, coughing, and chest tightness. Asthma is a chronic condition and is not curable. Asthmatics can have multiple triggers/allergens that lead to attacks.
Cold Induced Asthma is different from Asthma. It is a form of Angioedema where unlike hives which are on the surface of the skin and itch, the reactions are either below the skin surface or within the lining of the respiratory (and non-pulmonary areas like the digestive) tract. Those with Cold Urticaria or other Cold Allergies are susceptible to asthma like reactions when running, playing hard which increases frequency and volume of breaths entering the lungs or prolonged exposure to cold air, which increases chances for anaphylaxic reactions.
Increased levels of IgE may contribute to symptoms of Asthma.
The Connection Between Eczema, Asthma and Other Allergies (Including Cold Allergies)
Many young children who get a severe skin rash develop asthma months or years later. Doctors call the progression from eczema, or atopic dermatitis, to breathing problems the atopic march.
According to the World Allergy Organization, Atopic eczema is eczema with demonstrable IgE association.
